MATLAB: How to slow down a Simulink (R2015a) model so I can watch the dynamic behavior on a plot

Communications Toolboxconstellation diagramsimulinksimulink plots

My simulating model appears to run so fast that I cannot watch the dynamic behavior on a plot. It is as if the plot window is only updated at the end of the simulation run. My particular problem is with the "Constellation Diagram" in the Communications Systems Toolbox.

You can use the Real-Time Pacer block from the following File Exchange entry to slow your model down to CPU clock "soft" real-time.

MATLAB: Directory Watcher

You can use recursive directory listing in the following way:

dirs = folderSizeTree('D:\');;

Then you can store results across days and use setdiff to find which new folder were added.

MATLAB: Non-real time simulation with Arduino

MATLAB/Simulink runs on Windows, Mac and Linux; none of which are real-time operating systems. Therefore, in general, MATLAB/Simulink are not recommended for real-time simulation. There are two add-on products that are available for true real-time simulation: Simulink Real-Time (formerly xPC Target) and Real-Time Windows Target.

However, if you are designing for a soft real-time application, and your Simulink model runs faster than your application, you might be able to get away with this.

Do you plan to run your model in a loop with the hardware, or do you asynchronously request results from Simulink when inputs become available?
